    opcodes/arc: Support dmb instruction with no operands
    
    In this GCC commit:
      https://gcc.gnu.org/ml/gcc-patches/2015-12/msg00735.html
    GCC started emitting dmb instructions with no operands.  The intention
    was that dmb with no operands should be an alias for 'dmb 0'.
    
    The following patch extends the arc opcodes library to support dmb with
    no operands.
    
    opcodes/ChangeLog:
    
    	* arc-tbl.h (dmb): Add a no operand version of dmb.
